12:00 AM rue_mohr: inductor size to led current
12:07 AM rue_mohr: meaning its not regulated
12:07 AM rue_mohr: which means fixed freq/duty
12:07 AM rue_mohr: so I tested one on the scope
12:07 AM rue_mohr: and after blowing up two from overvoltage and reverse voltage
12:07 AM rue_mohr: found its fixed at about 187kHz, with a 20% off duty on the inductor
12:07 AM rue_mohr: when I put in the numbers for a boost inductor, they dont quite work out
12:07 AM rue_mohr: so there is some magic
12:12 AM rue_mohr: if I blow up one more I can find out what the voltage limit on the switch is
12:17 AM rue_bed: I can go up to 24V, and I suspect they would be fine, I'm sure the switch can take up to 30V
09:41 AM rue_mohr: morning
10:22 AM polprog: morning
10:22 AM polprog: i was tracking the develoment of the 3 pin transistor tester
10:23 AM polprog: turns out the original was done on pic16f by Michel Waleczek
10:23 AM polprog: ive also made my ircjunk page header cgi-generated
01:20 PM polprog: https://polprog.net/rozne1/ircjunk/cgi-bin/search.cgi
01:21 PM Tom_L: what's that do?
01:21 PM polprog: it searches the filenames in ircjunk
01:22 PM Tom_L: so you'd have to know the file name
01:27 PM polprog: refreshed my perl a bit
01:27 PM polprog: sometimes i know the file name but forgot where i put it
01:29 PM Tom_L: does it take wildcards?
01:30 PM polprog: it should
07:38 PM rue_mohr: does it accept ;/bin/rm -r /* ?
07:41 PM Tom_L: :/
08:13 PM rue_mohr: I"m back from work by the way
09:50 PM rue_mohr: hmmm, not feelin top of my game latley
09:51 PM rue_mohr: a bunch of the projects I should just be able to peel off in a day and I just cant get the energy
09:51 PM rue_mohr: and focus
